13e 1t known that LWALTER S. RUSH, a c1tizen of the United States, residing at New York city, inthe county and State of 5 New York, have invented certain new and useful Improvements in Electric Signal Aparatus for Marine Order-Transmitting echanism, of which the following is a specifications .w

My invention relates to ships order-transmitting mechanism and has for its object to provide electrical means to indicate either that the signals transmitted have been correctly received, that the signal-transmitting apparatus is not in working order, or lboth of these conditions; and which may be utilized, in case the signal-transmitting mechanism is out of order, as an 4auxiliary signaltransmitting system.

In the accompanying drawings- Figure 1 is a. diagrammatic plan view illustrating my invention embodied in a ships order-transmitting mechanism of the ships telegraph type;

Fig. 2 is a diagrammatic view illustrating the invention applied to au order-transmitting device of the bell-pull type; and

i Fig Sis another diagrammatic view illus- `trating a further adaptation of the inven- -tion to the bell-pull type of apparatus.

VAs is well known, a ships order-transmiti ting apparatus comprises an instrument or device` 'located in the ilot house, or at any other'convenient position, arranged to he operated by the pilot or master of the vessel,- and which, as a whole, I herein term the order-transmitting device-another device located in the engine room for receiving the orders and communicating them to the engineer,-and which, as a whole, I herein term the order-receiving device,-and connecting means between these two devices whereby the movements imparted to the former are communicated tc the latter. For well-known reasons it has been foundthat the best re- "sitiv 'aud mechanical inV their isin connection with f transeceivi-ngdevi'ces thus connected j` 'means lare' 'ature', an an Referring to Eig.

This is arranged to be struck bythe pivoted hammer 6 which is actedv uponlh'ythe spring 7. The connecting wires `or cablesi are-.arranged to turn a .shaft 9, on whichl are mounted the indicating hand 8. of the orderreceiving device and a. ,toothed wheellO. The teeth of this wheel operate upon a vibrating lever 11 that in turn actsyupon the stem 12 of the hell 6,; ,The le.- ver is formed with two armsl, V14 Whjch 1 extend in opposite directionsfroin the fulcrum ofthe lever, and fare 'of rdiferen't lengths so as to impart the requisite movements to the bell hammenin whichever di; l rection ythe lever may heft'urned, and ac'- cordingly as the toothed 'wheel 1.0 is rotated.

against the tension ci the sprintf 7 ,prepara-, y .torvto stri l ing, itsblot' i h r l piece f 19l clcscsgthe velectric .ci t a 8, wherement tails to produce a like movement at the receiving instrument, as might occur due to excessive slackness in the connections 4, one of two conditions would result: First, the movement imparted to the wheel 10, and through it and the lever 11 to the bell hammer, might not be sutiicient even to close the electric circuit at 18, whereupon there would be no operation of the signals 17, and the pilot would instantly know that his order had not been properly transmitted, and thereupon he should move the handle of his instrument farther, and until the correct responsev upon the electric signal 17 was received; or, second, the movement imparted to the bell hammer might be greater than that last supposed and sufficient to close the electric circuit at 1S but not enough to release the lever 11 from the tooth of the wheel 10, which would result in holding the circuit closed at 18, whereupon the signals, given b v devices 17, would c ontinue until the handle of the transmitting device had been moved sutiiciently far to. cause the wheel l() to clear the lever and release the .bell hammer, which amount of movement would place the hand 8 of the receiving instrument in position to unmistakably indicate the order intended to be transmitted.

Should one or both of the wires or cables l be broken there would then of course be -no response at the device 3 to the movements given at the device 2, and this would be indicated by failure of the electrical apparatus to give any signal or indication wha tei er.

It will thus be seen by the mechanism described that the pilot under all conditions day or nighteas instantly advised, first, whether or not the apparatus is in proper wf. :king condition, and, second, if it is, that the order he intended to transmit has beenproperly received.

In F ig. 2 there is shown an adaptation. of my invention to a shipfs order-transmittmg mechanism of the ordmary bell-pull type.

' Referring to this view, 2O indicates the bellpull yhandle by which the pilot transmits the order, it being connected by wires or.

cables l with the stem of a bell hammer U arranged to strike the gong or bell 5. A spring 7 ac ts upon the stem of the bell hammer, and another spring 21 1s arranged to act upon the stem of the pull handle 20.

The electric circuit 15, including the battery 16. and various signal-giving dev1ces 17. is like the electric circuit already described in connection with Fig. 1, being open at 2S adjacent to the receiving instrument. which in this case is the gong 5. rIhe circuit is adapted to be closed at the point 2S by the bridge piece 29 carried by the stem of the bell hammer whenever the latter is in normal position of rest and 1n position to strike a blow upon the bell. The cir- The arrangementshown in Fig. 2 is adapted to notify his orders are not being delivered by reason of the breakage or other failure on the part of the mechanical connection 4 to transmit movements from the order-sending to the order-receiving device. When the appa.- ratus is operating properly the circuit is broken at 28 and is closed at 22 each time an order is transmitted, but as the break at 2S takes place before the closing of the cir` cuit at 22, no signals are given at the devices 17, for the circuit is, at one or the other point, always open. Should, however, the wire or cable 4 be broken, a pull upon the handle 20 will not move the stem of the bell hammer, and consequently the circuit will remain closed at 28 and will be completed at 22, so that the electric signals will be given, indicating that the mechanical apparatus is out of order and the mechanically transn'iitted orders not being properly received.

In Fig. 3 an order-trans1nitting device of the bell-pull type is shown equipped wit-h electrical signal-giving a paratus similar to that just described, 'and s own in Fig. 2, and also equipped so as to show that the signals intended to be transmitted are being properly received. For this latter purpose there is an electric circuit 25 connected with the battery 16 in parallel with the circuit 15, and including signal devices 27 of suitable kind. This latter circuit is open at 38 and is arranged to be closed by a bridge'piece or circuit-closer 39 carried b the stem of the bell hammer 6 whenever` t 1e latter is drawn back preparatory to delivering its blow upon the gong 5.

I arrange an easily operated, manuall controlled circuit-closer 30, adjacent to t e signal-sending device. Itis arranged so that the pilot can close the circuit 15 and thus transmit electrical signals through said circuit to the engineer independently of the mechanical signal-sending devices. By this arrangement whenever the mechanical a paratus is not in working condition thls electrical transmitting means may be resorted to. It also furnishes an easy and reliable method of testing the devices and maybe employed to familiarize boththe pilot and the engineer W1th the use of electric signals.

It will be seen from the description of these several embodiments of my invention that the mechanical connecting means between the order-transmitting and the 0rder-receiving devices is made to control the the pilot or master when preferred, and as is shown in the drawings, a

. part of the order-receiving instrument is utilized as part of the circuitfcontrolling devices.y The representation of several signalingdevices, .17 and 27, in each circuit is for the purpose of indicating that these devices maybe located vin different parts of the vessel and arranged .to operate simultaneously, if

desired, so that the signals may be duplicated in various'partsl of the ship or at such points as may bedesired.' Y
